Scalar-induced gravitational waves from inflation with symmetry breaking
Chong-Bin Chen, Jia-Xi Feng, Fu-Wen Shu +1
We investigate scalar-induced gravitational waves (SIGWs) in an inflationary model with symmetry breaking, in which charged scalar fields are coupled to an isotropic triplet of Abe…
Curvature-induced scalarization of charged AdS black holes
Chao-Ming Zhang, Yun Soo Myung, Lina Zhang +2
We investigate how a negative cosmological constant affects the Gauss-Bonnet (GB) scalarization in the Einstein-Maxwell-scalar-Gauss-Bonnet theory with a scalar coupling constant $…
Bound-State Resonances of Schwarzschild-de Sitter Black Holes: Analytic Treatment
Qi-Dong Chen, Chong-Bin Chen, Guo-Qing Huang +2
Inspired by Mashhoon's framework connecting black hole quasi-normal modes (QNMs) to bound-state resonances in inverted potentials, Vlkel's recent numerical analysi…
Inflation with shallow dip and primordial black holes
Bao-Min Gu, Fu-Wen Shu, Ke Yang
Primordial black holes may arise through ultra slow-roll inflation. In this work we study a toy model of ultra slow-roll inflation with a shallow dip. The ultra slow-roll stage enh…
